Engine/Transmission (1998.5 - 2002) Torque converter

[Rockcrusher]

I have been reading latest issue and manual with interest and trying to determine at what speed/rpm converter is supposed to lock up?

Manual indicated PCM dictates when lock up occurs. What is the input to PCM; apps, throttle sensor or what?

I would assume when up to speed lock up should still be engaged even when you let up on throttle. I have noted that rpm goes down to idle even at high speeds when I let up.



Also I have been looking through all the graphs trying to find the "sweet spot" rpm for best efficiency. I try to keep it @2,000 rpm.

Diesel is running $339. 00 in my area so trying to get the best milage.

Mine does the same thing, idles when off the throttle, and my TC locks between 40-45mph when I'm driving normally ... with 410 rear.



For what it's worth, your getting a deal at $3. 39 ... $3. 49 here and that's the cheap places!
